❓ Reduce release bundle size

[PavelRazumov]

Question

Hi, team.

I use this library only for reading barcodes. My question is is there an opportunity to reduce the size of the bundle of the final release application? As an example for comparison, I created two applications using npx react-native init https://reactnative.dev/docs/environment-setup (version 0.66.0), and for one of them I added the react-native-vision camera library (version 2.13.2) with reanimated (version 2.4.0) and launched the release build with the minifyEnabled true flag

// Empty app

// App with react-native-vision-camera

Is there any solution to optimize the releaser apk build ?

What I tried

1. Create two empty projects with help npx react-native init
2. One of them add dependencies react-native-vision-camera, react-native-reanimated and vision-camera-code-scanner
3. Launching release build for both app with flag minifyEnabled true.
4. Check apk's result

VisionCamera Version

2.13.2

I try add compile flag like -Os or -O3 (https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#Optimize-Options) in build.gradle in react-native-vision-camera, but unfortunately it didn't work

In my case, i was set minSdkVersion = 23 and apk size is increased. Finally i change it to 21 .

I will back later to share the information source

EDIT:

https://github.com/zoontek/react-native-bootsplash/issues/288#issuecomment-981907888 I got information source from this comment. So my android/build.gradle look like below:

....

buildscript {
    ext {
        buildToolsVersion = "31.0.0"
        minSdkVersion = 21 // <= set to 21
        compileSdkVersion = 31
        targetSdkVersion = 31
....

I hope it can help you...

@babaiyu, hi,

I don't understand, what do you mean about minSdkVersion and boostsplah? In my question i want to reduce size of react-native-vision-camera only, and my minSdkVersion is 23 it's actual version of Android 6 (out minimal support version)

Nevermind with bootsplash, it just example case to other libraries hehe.
